Abstract

Forty-eight male and 48 female Florida Sevillana kids, from twin births, were slaughtered al 30,45 and 60 days. Half of each group were raised with maternal milk and the other with milk replacer. They were slaughtered, following Colomer-Rocher et al. (1987) methodology. The left half-carcase, weighing 2.02-3.54 kg, was cut into 5 joints. The heaviesl was the leg (32.&33.4 p.100 ), followed by ribs (25.2-26.2 p.100), shoulder (19.7-20.6 p.100), flank (10_2-12.4 p.100) and neck (8_8.9.7 p.100). There were few differences between feeding methods. Males showed greater development of the rear quarter. while females did so in the trunk and shoulder. Grouped in commercial terms, prime joints represented 58.59 p.100, first-class 19.20 p.100 and second-class 20.22 p.100. Allometric coefficients from the differents joints revealed early maturity for shoulder, neck and leg. The growth of the ribs was isometric and the flank showed late matunty. Differences were recorded between sexes and feeding methods. Muscle, bone and removable fat represented 57-58 p.100, 22.25 p.100 and 15.19 p. 100, of total carcass weight, respectively. Intramuscular fat (9.7-11.8 p.100) was the most important. followed by subcutaneous (5-6 p.100) and pelvic fat (0.6.0.7 p.100). While the liveweight increase, bone weight fell, muscle remained the same and the removable fat also increase. Muscle/bone and muscle/fat ratios reflected meaty. well fatted carcases. The leg and shoulder were the joints with the highest muscle and bone content, while the most fatty joints were flank and ribs.
